fails to install or remove upon dpkg or apt-gotten for install

There is no bug that I can see; your file system is possibly corrupted since the error is:

dpkg (subprocess): unable to execute post-installation script: Exec format error

coming from libgnome-cni, which is however fine if I check your arch/version in the archive.
Can you give this command in a terminal an attach here the resulting postinst file:

cat /var/lib/dpkg/info/libgnome-cni.postinst > postinst

?

here you go.thought so, but not sure how it happened.all i did was base
install on ppc and add some packages i needed, moreso from a dselect, as
it takes quite some time to install apps otherwise.i copied my home
folder from a intel box, but that shouldn't mess things up.

Your postinst seems to be fine.
Can you check if that file and /var/lib/dpkg/info/ have the executable bit set? Can you check if /var is mounted with the exec flag set?
Can you try to manually execute that script?
If worst come to worse, you can try to force the installation with:

sudo dpkg --force-all -i /var/cache/apt/archives/libgnome-cni_2.12.7-4_powerpc.deb

Its a dangerous command to give, so try other solutions first.
This may not solve others problem you have which could be related to a corrupt file system but at least should solve this one.
Anyhow, I'm transforming this into a question since there doesn't seem to be any bug.

I just stumbled against this reply by pure chance. Pls. do not add comments to a bug report marked invalid, they won't be seen by anyone.
As for your question, probably you have cleared your apt cache. Try downloading the deb package and then retry the command (but change the path to the location where you saved the deb package).

As for how your file system is corrupt, I can only guess a power outage, or perhaps a buggy kernel driver, who knows.
